ABSTRACT

Techniques for searching for a user interface (UI) are provided. The techniques include receiving a desired user interface as a query, determining meta-data for the desired user interface, wherein determining the meta-data for the desired user interface comprises converting the desired user interface query to a meta-data query, and using the meta-data query to search for the desired user interface, wherein searching for the desired user interface comprises querying meta-data of one or more existing user interfaces and selecting one or more similar user interfaces.

FIELD OF THE INVENTION

Embodiments of the invention generally relate to information technology, and, more particularly, to user interfaces.

BACKGROUND OF THE INVENTION

Software with a graphical user interfaces (GUIs) often contain many different user interfaces (UIs) that differ from each other based on various qualitative aspects.

Such aspects can include, for instance, low-level controls that make up the interfaces (for example, button, text box, combo box, etc.), layout of controls (for example, grid layout, free form layout, etc.), position of individual controls (for example, button on top, button on bottom, etc.), labels associated with controls (for example, ‘Click’, ‘Press’, ‘Submit’, ‘Go’ on a button), look and feel of controls (colors, borders, transparency, themes, etc.), behavior of controls (read only, clickable, trigger asynchronous request, etc.), content of controls (for example, all labels with “Name” in them, or all dropdowns for geography selection).

Given the various functional requirements, user interface designers can often spend time designing interfaces trying to achieve the right combination of the above qualitative parameters, which impact the overall interface. The process is highly iterative because designers have to attempt many kinds of interfaces until an interface is discovered that best suits the interest of clients. Additionally, given a set of requirements for the above parameters, the designers may end up redesigning an interface which already exists somewhere else in the larger software system or collection of software systems.

As such, challenges include, for example, within the realm of the interne, where a lot of UI designers spend considerable effort designing a web page, similar pages have already been designed and exist in other websites.

DETAILED DESCRIPTION

Principles of the invention include indexing and querying user interfaces (UIs). One or more embodiments of the invention include indexing user interfaces based on searchable metadata, and allowing users and/or clients to search for desired interfaces based on the querying the metadata. Additionally, the techniques described herein can include a mechanism of querying for user interfaces similar to a desired user interface by choosing and/or creating the desired user interface graphically on a graphical editor.

As detailed herein, one or more embodiments of the invention include using metadata of user interfaces to index the user interfaces such that similar interfaces can be searched from a large collection of existing user interfaces. Such a step can be performed, for example, by a user interface index engine, which indexes various metadata attributes of the user interface. Also, the techniques described herein can include specifying the query for the desired user interface as another user interface that can be constructed (for example, by a user) using a graphical user interface editor or chosen from an existing list of user interfaces. Such a step can be performed by a user interface query translator, which converts a graphical user interface selected/created by users to a metadata query which can be then executed on the index to return a set of similar user interfaces.

Further, unlike the disadvantageous existing approaches, one or more embodiments of the invention include indexing existing user interfaces based on the qualitative description (that is, meta-data or specification) and using this index to query for user interfaces based on the required metadata or specification.

As detailed herein, user interfaces include user interface elements (such as text input, text area, etc.) and their layout, content that is rendered using these elements and interaction points (such as back-end events or java scripts, etc). The meta-data of an entire user interface can, in turn, include capturing the meta-data around these dimensions. In one or more embodiments of the invention, a repository of such meta-data (extracted from various user interfaces) is created.

FIG. 1 is a diagram illustrating components used in the techniques described herein, according to an embodiment of the present invention. By way of illustration, FIG. 1 depicts a query front end module 102, a UI builder module 104, a direct declarative query module 106, a graphical user interface (GUI) interpreter module 108 and a UI meta-data based query module 110. FIG. 1 also depicts a query engine interface module 112, along with a UI meta-data based index module 114, a UI meta-data extractor module 116 and a system/UI interface repository module 118.

Existing user interfaces are stored in the system/UI interface repository module 118. UI meta-data extractor module 116 extracts the meta-data of the user interface in the repository and the UI meta-data based index module 114 indexes the existing user interfaces based on the meta-data extracted.

The end-user that requires a particular user interface can describe the user interface using a graphical editor (for example, component 104 in FIG. 1). The graphical editor provides a palate include all user interface elements along with properties specification editor (for layout, style properties, etc. to be specified). The user interface thus created is interpreted by a GUI interpreter module 108, which extracts the meta-data. The data is then passed to a UI meta-data based query module 110, which constructs the meta-data based query and invokes the query engine interface module 112 to search for related user interfaces. Suitable matches of user interfaces based, for example, on their rankings, can then be returned back to the end-user.

User interface elements have various properties to capture or characterize them. By way of example, these properties can be characterized as basic, style and behavioral properties. Basic properties are properties that define what the user interface element is. For example, for a text box, type (to determine it is text box), width, height, password (true if takes in a password field) are basic properties. Style properties define the look and feel of the user interface element. For example, color, font size, back ground color, border style, etc. are style properties. Behavioral properties define the behavior of the user interface element in terms of the possible events/user interactions allowed on it. For example, behavioral properties can include whether a user interface element can be clickable or not, and if clickable, how it behaves; whether a UI element invokes a client side script or invokes a back end service call, etc.

These groups of properties constitute the meta-data of a given user interface element. For a given page (user interface), there can also be extra information captured along with the meta-data of the user interface elements in it. For example, at a page (user interface) level, the overall structure or layout of the user interface element is a noted attribute. The following high level structural elements, as described herein, can be used for any user interface.

Additionally, content properties are the properties that represent the type of content being displayed in a user interface based on the semantics. For instance, examples can include all labels with the text “Name,” or all drop-downs which allow selection of a country. One or more embodiments of the invention also include blocks (fragments) and containers. Each page can be considered to be split into blocks such as, for example, header, footer, content area, navigation panel, etc. Each block can directly contain the user interface elements or can further contain structural elements called containers. Containers include various types such as, for example, list container, news paper container, data layout container, etc. Each container can include either containers or user interface elements.

The property set of basic, style and behavioral also applies to containers. Given these structural elements and user interface elements, the meta-data at the page (user interface) level can be captured as a nested-graph of such elements. At a top level, the meta-data for the page (user interface) can be a graph where each node is a block. The edges between these blocks have an edge property, which captures the distance, position (left, right, up, down, etc.) of each block with respect to each other and the overall page width and height. Each node (block) in the page graph can have block-sub-graph associated therewith, where each node can be either user interface elements or containers. The edge property can again be applied here to the edges between the nodes, which captures the distance, position (left, right, up, down, etc.) of each node (user interface element or container) with respect to each other and the overall block width and height. If the block sub-graph contains any container nodes, each container node can have a container-sub-graph associated therewith it, where each node can be either containers or user interface elements.

The meta-data of the page can include a set of graphs and sub-graphs with properties (basic, style and behavioral) at each node and properties (distance, position) at the edge. For a given page, the meta-data can be, for example, a graph of user interface elements, or a nested graph of containers and user interface elements or a nested graph of blocks, containers and user interface elements. The repository can be populated with this meta-data information by parsing available user interfaces.

FIG. 2 is a diagram illustrating a graphical representation of the meta-data for a particular page, according to an embodiment of the present invention. By way of illustration, FIG. 2 depicts a sample user interface 202, and page graphs (with blocks) 204 and a UI element graph 206. Given a user interface 202, the corresponding meta-data that is extracted is a set of graphs. The top level page graph 204 depicts the components that depict the UI. The nodes of this graph can be blocks like header, footer, navigation area, content area, etc. Each high level block can in-turn include UI elements and the detailed UI element graph 206 captures the layout and details of the UI interface elements within a particular block. There can various properties (basic, style and behavior) that are associated with each node and edge in the graphs.

As detailed herein, one or more embodiments of the invention include a search query for searching the meta-data. By way of example, a user can describe the desired user interface using the graphical editor. The UI could be detailed completely (high-fidelity) or it can be just a rough sketch (low-fidelity). Additionally, one or more embodiments of the invention can follow the same meta-data extraction principle explained above to extract the meta-data for the desired UI. This meta-data (graph with sub-graphs) of desired UI becomes a search query. This query can then be searched against the set of meta-data of available UI stored in a repository. Further, the searching can reduce to a graph (sub-graph) matching problem.

The graph property of the desired UI can be identified as to whether it is block, container or UI element level, and based on it, compared against the corresponding level of the meta-data graph available in the repository. The matches that are found can be ranked based on the degree of match. The degree of match can be determined, for example, by the extent up-to which the properties of the graph match with each other. In one or more embodiments of the invention, once the list of matches is available, the UI pages are returned with the portion of the desired UI highlighted therein.

FIG. 3 is a diagram illustrating searching for a desired user interface, according to an embodiment of the present invention. By way of illustration, FIG. 3 depicts an end user 302, a graphical UI editor module 304, a query builder module 306, a user interface library module 308, a meta-data extractor module 310, available user interfaces 312, a meta-data repository module 314, a search engine module 316 and a search results editor module 318.

As depicted in FIG. 3, an end user 302 uses the graphical UI editor 304 to create the desired user interface. The desired user interface is then taken by the query builder module 306 and a meta-data based query is constructed for the desired UI. Search engine module 316 takes this meta-data based query and searches it against the metadata repository 314 of available user interfaces. Based on the degree of matching of the meta-data, the search engine 316 can prepare a ranked list of the search results of the matching user interfaces. The search engine 316 also adds in meta-information to mark the sub-set of the matched user interface in the user interfaces in the result.

The search engine can also send these results to the search result editor module 318, which can show the list of matching user interfaces, complete, for example, with the matched portion highlighted. The list of matching interfaces can contain interfaces from various different repositories based on different technologies. The end user 302 can view the available user interfaces and view their source (for example, hypertext markup language (html), language specific code, etc.) content and re-use them.

As also depicted in FIG. 3, the meta-data extractor module 310 crawls through the available list of user interface 312 (for example, on the web) and extracts the meta-data for these user interfaces. The crawler can also extract user interfaces from existing code repositories of libraries (for example, user interface library module 308) which contain the language specific user interface implementations. The meta-data extractor module 310 can store these meta-data into the meta-data repository 314, as well as create and index these based on certain meta-data properties such as whether the meta-data is for page, block, container or user interface element level, etc. Additionally, the meta-data extractor can be fed a set of user interfaces offline, which it can parse to extract the meta-data. These offline user interfaces can be available, for example, in the user interface library 308.

One or more embodiments of the invention can also be used, for example, to create a searchable repository for common UI patterns. As such, UI designers/developers can search based on low fidelity design mockups to get the corresponding high fidelity implementation code. Also, the techniques detailed herein can be used to build a catalog of reusable UI components in various UI implementation tools.

FIG. 4 is a flow diagram illustrating techniques for searching for a user interface (UI), according to an embodiment of the present invention. Step 402 includes receiving a desired user interface as a query (or, for example, a mock-up). Step 404 includes determining meta-data for the desired user interface, wherein determining the meta-data for the desired user interface comprises converting the desired user interface query to a meta-data query (for example, via a UI query translator).

Step 406 includes using the meta-data query to search for the desired user interface, wherein searching for the desired user interface comprises querying meta-data of one or more existing user interfaces and selecting one or more similar user interfaces. Designing the desired user interface can include using the meta-data query to construct the desired user interface using a graphical user interface editor.

The techniques depicted in FIG. 4 can also include forming an index by indexing meta-data attributes of existing user interfaces (for example, using a UI index engine) based on searchable meta-data. One or more embodiments of the invention can additionally include indexing existing user interfaces based on one or more qualitative descriptions (for example, specifications). Querying meta-data of existing user interfaces and selecting similar user interfaces can include, for example, using the index to query for a user interface based on the determined and/or required metadata of the desired user interface.

One or more embodiments of the invention can also include using the index to create a searchable repository of common user interface patterns. Additionally, the techniques detailed herein can include searching the searchable repository of common user interface patterns based on a low fidelity design mockup to determine a corresponding high fidelity implementation code. One or more embodiments of the invention also include using the index to build a catalog of reusable user interface components in user interface implementation tools. Further, the techniques depicted in FIG. 4 can include providing a mechanism to construct the query visually.

The techniques depicted in FIG. 4 also include searching the searchable repository of common user interface patterns by specifying faulty and/or standard interface queries to enable filtering out of faulty interfaces and those that do not adhere to a set of standards, enabling testing and verification of one or more user interfaces. Additionally, UI developers can also use one or more embodiments of the invention to test and verify all developed user interfaces from a repository by providing a user interface query corresponding to a faulty interface or a standard interface and analyzing the returned interfaces. Also, in the “UI as a service” scenario, one or more embodiments of the invention enable selection of a desired interface from a set of multiple UI services available to render the same information, by specifying the desired interface in form of a metadata query, which can then be run on all the existing UI's available to return the most similar UI and appropriately select the corresponding UI service.

The techniques depicted in FIG. 4 can also, as described herein, include providing a system, wherein the system includes distinct software modules, each of the distinct software modules being embodied on a tangible computer-readable recordable storage medium. The distinct software modules can include, for example, a user interface query translator module, a user interface index engine module, a graphical user interface editor module and a meta-data extractor module executing on a hardware processor.

Additionally, the techniques depicted in FIG. 4 can be implemented via a computer program product that can include computer useable program code that is stored in a computer readable storage medium in a data processing system, and wherein the computer useable program code was downloaded over a network from a remote data processing system.
